Could not find "pppd" binary

2016-03-14 Thread Ali Nematollahi 
Hi guys

I finally got MM 1.4.12 and 1.0.10 working and talking to each
other...after a long battle.
I got NM to a point that it detects MM and after all MM set up is done, it
tries to bring up the connection I have up but it fails saying pppd binary
not found. I compiled the NM with the option --with-pppd= but it still says
that.

Any idea why? Should I switch to PPP service provided by NM? Is it stable
and ready to use in a production environment? How do I make the switch?

Thanks!

That is trying to launch the old ModemManager, which has a different bus name.

You need to configure NetworkManager explicitly with
"--with-modem-manager-1", or explicitly add ModemManager libraries as
build dependency on your yocto recipe, so that the requirement of
"--with-modem-manager-1" is detected automatically.

Yeah, ModemManager chokes on the split PDP context IDs.  Does this

Yes, mmcli seems workin quite nicely - no problems at all.

Re: nmcli radio off connected to ModemManager power state low

clear, the same as mine.

So, saying that my targets are ModemManager Telit plugin's modem_power_down
and modem_power_off functions, we have:

* modem_power_off (which is not implemented) == power off.
  Ideally, CFUN=0 would be the candidate, but it would make the modem
unrecoverable, so CFUN=4 would be my choice, which is OK, if I understood
correcly.

* modem_power_down is currently implemented with CFUN=4 so == radio off.
  However, considering that it is activated with "mmcli -m 
--set-power-low", it looks to me as a function that puts the modem in a
"power saving state", for which Telit's CFUN=5 would be more appropriate.
  The problem is that if I change modem_power_down to CFUN=5, when I use
"nmcli radio off" ModemManager will send CFUN=5, which is not a "radio off"
state.
  So, the question is, "mmcli -i  --state-power-low" is to be
considered like "go to power save" or "radio off"?

But, if I got it right, I can't override mm_modem_disable for a plugin,
right? When I disable the modem (mmcli -m ID --disable) no AT+CFUN command
is sent to the modem.

I guess that moving in and out from a power saving state would cost some
time (and maybe overhead?) respect CFUN=1 which should be more responsive.
Moreover, I would expect to get into a power saving state issuing
--set-power-low more that with --set-power-on.

Reading further, if CFUN=5 gets used then the telit plugin would need
some special handling of DTR and CTS it seems.  So it won't be trivial,
but probably worthwhile anyway.  We'd probably need some MMPortSerialAt
support to handle the DTR drop and then wait-for-CTS on DTR on, but
that's OK.

I'm not entirely sure what you mean with "power off" and "shut down the
radio", but here are the definitions I'm using:

power off: the entire modem is powered off not just the radio.  The
device does not communicate with the host because it is unpowered.

radio off: the radio is powered down and no network communication is
possible, but the modem can still communicate with the host.

The ModemManager API specification would not allow CFUN=5 for the
"disabled" state, since it defines the disabled state as not allowing
network communication.  So I would still use CFUN=4 for "disabled"
state.  But couldn't the modem instead be set to CFUN=5 whenever it is
enabled?  The Telit docs seem to say it's a fully functional state,
just that the modem can do some power saving.  Which sounds like a win
without a downside.

I tested that with a bunch of USB modems, and only a small number (2
out of 20 I tried) actually powered completely off with CFUN=0.  The
rest apparently just disable the radio but remain responsive.

This means that NetworkManager cannot see ModemManager on D-Bus.  Does
'mmcli -L' produce any output?

In fact there are two more messages preceding those ones I mentioned
before, but I guess they have nothing to do with this problem. I'll get
following messages, if I have MM running from boot:

There was also other one besides these (re)launch messages. The first
message was:

then repeating gradually:
Requesting to (re)launch modem-manager...

I tried it now: NM can't communicate with MM. There is only one type of
message related to modem-manager:

Did you try to run NetworkManager with debug logging? IIRC, the modem
management code in NM does print several debug logs when watching MM
in the bus.

Yes, indeed.
BTW, I just monitored dbus traffic (dbus-monitor --system) and it seems
that all the information received by mmcli is seen from this monitorin
session.

nmcli c does not list modem device

2016-03-14 Thread matti kaasinen 
Hi!

I can't get modem device listed with
nmcli c
command. So, NM does not see it and therefore it can't start connection
with NM.
Last week it worked fine. I wrote python code for bringing gathering up
data from from modem interfrace for NM. Then NM could identify this modem
and I got 'DeviceAdded' signal. Now NM can't detect modem and I don't get
this signal.

Modem manager procedes up to:
export_modem(): (/org/freedesktop/ModemManager1/Modem/4): 'Huawei' modem,
VID 0x12D1 PID 0x1506 (usb)

Device is quite well accessible with mmclient.

Platform is yocto based am335x board running on Linux 4.1, NM version
0.9.8.10, MM version 1.4.2. I have patched MM with commit number
359ec84671f9fc0869443b9f0b9555324a0fff78 to fix Huawei AT^NDISDUP problem.
Last week it worked fine.

Aren't NM and MM discussing through dbus? Only difference that I can figure
out is that now I have built python-networkmanager into image. Could that
disturb somehow?
What could prevent NM from seeing modem devices?

Cheers,
Matti
